I have one as well. Waiting for rep to respond. I've had mine leak twice, but it's been fine since. Ford in the interest of customer satisfaction authorizing dealer repair free of charge regardless of mileage. It's a repair or replacement whichever the dealership feels best. I know the dealership I use will push not to replace it because they don't want to do the work. And it hasn't been leaking. Ford is saying talk with dealership they are authorized under the satisfaction program to repai/replace it.I also saw this today, no info and very cryptic. The only possibility I saw expressed on another forum for "trough" was something to do with moonroof drainage.
